The node supervisory unit includes an alarm indication information storage unit that manages a management table for each of the plural directions. The management table manages not only received alarm indication information but also “internal WSS input/output port optical fiber connection state”, “WSS optical path setting state on DROP/THROUGH selection side”, “transponder destination location”, and “destination direction”, with respect to each direction. Then, a process flow is added to match received FDI information with the management information stored in the management table for each direction, and to specify an alarm destination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical cross-connect apparatus","description":"The present invention relates to an optical cross-connect apparatus supporting plural directions, and provides a method of effectively performing an alarm indication by a node supervisory unit of the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8498537","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
